Gpu problem??

[jonleeprice]

Hi all im new here i have a question i really could do with a straight answer (not always easy i know) anyways..

Specs first...
Cpu-2gig phenom 1 quad Before update (1090t)
Ram-4gig (3.4 with win 32)
Gpu- gainward gtx 460 1gig

Anyways.....

I installed a new cpu a couple of weeks ago (1090t) all working fine, i decided to Oc it (never done this before) as soon as i left the Bios i had a blank screen pc running ok be the sound of it, so i restarted a couple of times....pc is booting fine (by the sound of it) but i have a blank screen.
I installed my OLD hd4650 and it worked fine had image on the screen and everything, turned pc of turned it back on later on and same thing had happend pc booting ok but blank screen, so i took it out and booted without a gpu.....again it worked fine then stupidly i thought "lets make the onboard gpu active)"...........this black screened straight away.

Anyone got any ideas? its like the monitor is just getting no signal from the gpu's?

Monitor is fine as i have since used it for xbox and this old pc i am on now.

Thanks in advance Jon

Did you turn the clock speed back down? Theres several possibilities if its still clocked up, one is the memory cant take it and another is the pci-e slot is being increased and the video cant take it.

theres a difference in powering up and booting up, just because it powers up (fans and drives spin) doesnt mean its booting.
